Línea de transmisión cuasi-óptica con modos gaussianos de orden superior para sistemas basados en gyrotrones tecnológicos para aplicaciones cerámicas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a description of a new compact microwave oven system based on a tecnological
gyrotron for material processing applications is presented. The whole system has been designed by the
Institute of Applied Physics ...
New approach to the design of corrugated horn antennas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present two new corrugated horn antenna designs in circular waveguide. The first one is a
converter horn antenna from monomode circular waveguide TE11 to corrugated waveguide HE11 mode in a very efficient ...
On the determination of the phase center of gaussian horn antennas
(1998)
Contribución a congreso / Biltzarrerako ekarpena,
Gaussian horn antenna designs have experimentally demonstrated excellent performance to produce a very pure Gaussian beam mode with extremely low sidelobes and crosspolarization levels. These results make very attractive ...
Generation of the HE11 mode in rectangular waveguide using gaussian techniques
(IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena,
A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 mode in a
corrugated rectangular waveguide, is proposed. The main idea ...
Measurements of a new gaussian profile corrugated horn antenna for millimeter wave applications
(IEEE, 1998)
Contribución a congreso / Biltzarrerako ekarpena,
The measurements results of a new design of corrugated horn antennas [1, 2, 3] following the
gaussian expansion are presented in this paper. The performance of two corrugated horn
antennas of this kind was verified in ...
Nuevas consideraciones al diseño de conversores de modos TE0m-TE0n para aplicaciones de alta potencia a frecuencias milimétricas
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the new results of a study about the general Kovalev’s coherence principle are
presented. As we will show here, despite Kovalev presents the coherence principle as general, only the
fundamental case can be ...
Consideraciones de paraxialidad en modos gaussianos de orden superior
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
Usually, the gaussian beam modes are assumed to be solutions of the wave equation in the free
space. Nevertheless, these modes are obtained supposing some paraxial restrictions. Therefore, we will
have to check if our ...
SCATTMAT: herramienta C.A.D. para el análisis de componentes en guía de onda circular con variaciones simétricas del radio
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a C.A.D. tool to simulate simmetrical radial deformation microwave devices, using
the modal analysis and scattering matrix techniques is presented. The code has been developed in C++
language, working with ...
High order mode beam waveguide for technological medium power millimeter wave applications
(1995)
Contribución a congreso / Biltzarrerako ekarpena,
The use of medium power millimeter wave CW gyrotrons (10-
30 kW and 30-100 GHz) has several potential applications in
advanced materials processing. Since a stochastic field
distribution in the applicator is desirable ...
Paraxiality considerations of higher order gaussian modes
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
Frequently, gaussian modes are used as free space wave equation solutions. This is not true since
they are obtained assuming certain paraxial character in them.
In this paper, we present an original study of the condition ...
